Review on Universal Plumbing Handle Emergency Replacement One by Pete Hahn

I'm not skilled, I don't know how to fix this thing. The handle on my outdoor faucet broke in half and I used a wrench to turn the water off. Ordered and installed in just 10 minutes. I took the handle half off, took off the bolt or nut or whatever and put it on. I followed the instructions and turned the manipulator, it worked. I don't know how it works or why it works, but it works. If I can do it, so can you.
